DEFINISI Balok,Kubus,Limas,Dan Prisma

1.DEFINISI BALOK

Balok adalah suatu bangun ruang yang dibatasi oleh 6 persegi panjang , di mana setiap sisi persegipanjang berimpit dengan tepat satu sisi persegipanjang yang lain dan persegipanjang yang sehadap adalah kongruen.

Bangun balok mempunyai ketentuan :

• Rumus Volume Balok = p x l x t (sebenarnya sama dengan kubus, hanya saja kubus memiliki semua rusuk yang sama panjang).
• Luas Permukaan Balok = 2 x {(pxl) + (pxt) + (lxt)}
• Keliling Balok = 4 x (p + l + t)
• Diagonal Ruang = Akar dari (p kuadrat + l kuadrat + t kuadrat)

2.DEFINISI KUBUS 

Kubus adalah suatu bangun ruang yang dibatasi oleh enam buah sisi berbentuk persegi yang kongruen

 Bangun kubus mempunyai ketentuan :

• Terdapat 6 (enam) buah sisi yang berbentuk persegi dengan masing-masing luasnya sama
• Terdapat 12 (dua belas) rusuk dengan panjang yang sama
• Semua sudut bernilai 90 derajat atau siku-siku
• Rumus Volume Kubus = rusuk x rusuk x rusuk (rusuk pangkat 3)
• Rumus Keliling Kubus = 12 x rusuk
• Rumus Luas Permukaan Kubus = 6 x rusuk x rusuk
• Luas salah satu sisi = rusuk x rusuk

3.DEFINISI LIMAS

Limas adalah bangun ruang yang dibatasi oleh sebuah bidang segi banyak sebagai sisi alas dan sisi-sisi tegak berbentuk segitiga.

Luas Limas = luas alas + jumlah luas sisi tegak

Volume Limas = 1/3 luas alas tinggi sisi

4.DEFINISI PRISMA 

Prisma adalah bangun ruang yang memiliki bidang alas dan bidang atas yang sejajar dan kongruen (sama), lalu sisi lainnya berbentuk jajar genjang atau persegi panjang yang tegak lurus ataupun tidak tegak lurus terhadap bidang alas dan bidang atasnya.

Luas permukaan prisma = ( 2 x luas alas ) + ( keliling alas x tinggi )

 Volum Prisma  = luas alas x tinggi.
